ERC-20 Standard

Architecture

The ERC-20 standard establishes a technical framework for fungible tokens on the Ethereum blockchain, mandating a specific interface that ensures consistent behavior across various decentralized applications. By defining a common set of functions, such as balance tracking and token transfers, the protocol facilitates seamless interoperability between smart contracts. This structural uniformity allows developers to build complex financial products with the assurance that all compliant assets will interact predictably within the broader network.
